IMPROVEMENT m BOLT AND ROD curngns.

Specification forming part of Letters Patent No. 137,956, dated April15, 1873; application filed March 25, 1873.

To all whom it may concern:

Be it known that I, S. H. PRESTON, of Worth, in the county of Mercer andin the State of Pennsylvania, have invented certain new and usefulImprovements in Bolt-(Jutters; and do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked thereonmaking a part of this specification.

The nature of my invention consists in the construction and arrangementof a bolt-cutter, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation,referring to the annexed drawing, in Which-Figure 1 is a side view, and Fig. 2 an edge view, of my bolt-cutter.Fig. 3 is a view of the cutting-dies.

A represents the lever for the left hand, and B the cutting-lever forthe right hand, the two levers being pivoted together at a. On the upperend of the lever A is a flange, b, projecting outward above the upperend of the lever B. On this side of the lever A, and against the flangeb, is secured the stationary die 0, the cutting-edge of which isconcave, as shown in Fig. 3. The upper end of the lever B, which formsthe movable cutter D, is convex, and pivoted eccentrically by the bolta. This bolt also fastens the upper end of a brace, D, on

the opposite side of the lever'A. The lower end of this brace is bent,as shown, and attached by a bolt, (1, to the lever B, the bent endforming a stop, E, against the lever A to protect the knuckles of theoperator. The bolt d passesthrough slots in the elbow or bend of thebrace D and in the lever B so as to adjust the stop as may be desired.In the upper end of the lever A, opposite the cuttingedges of the dies,is an opening, 6, for the bolt to be cut to pass through. H H are woodenhandles attached to the lower ends of the levers A and B.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. In combination with abolt-cutter, the adjustable elbow-brace D, forming the stop E,substantially as and for the purposes herein set forth.

2. The lever A, provided with the flange b, aperture 0, and stationarycutter O, in combination with the lever B pivoted eccentrically to thelever A, and its upper end forming the movable cutter D, all constructedand arranged substantially as and for the purposes herein set forth.

In testimony that I claim the foregoingI have hereunto set my hand this28th day of February, 1873.
